SYSTEMS AND METHODS FOR INTELLIGENT LIGHTING
First Claim
1. An intelligent lighting system for a parking garage, the system comprising:
- a plurality of lighting elements configured and arranged to illuminate one or more parking stalls in a parking garage;
a plurality of ultrasonic acoustic sensors configured and arranged to obtain occupancy data of the one or more parking stalls; and
a controller that is configured and arrange to use data from the ultrasonic sensors to control optical output of the lighting elements.

Abstract
Systems and methods are disclosed for the intelligent lighting of large areas and structures such as parking garages. Ultrasonic distance measuring sensors can be used to obtain occupancy data for the area or structure, such as a parking garage, and to control the intensities of the individual lights in the system for energy conservation. Persons in the area, e.g. parking their cars, can be shown the path to the exit by specific preset intensity level and/or color of light. In parking garage embodiments, persons in the process of parking their cars are shown the empty spots by lights of a specific intensity and/or color. The addition of passive infrared motion detectors enables the system to illuminate the area around a moving person, and alarm if a person is behaving unexpectedly. A controller can communicate with sensors and/or lighting elements by wireless or wire (cable) communication.
